To build Eddie Brock, for example, I need to mine sets like Lost Caverns of Ixalan for giant creatures that can have their mana value lowered for play, and later, sacrifice
Scrabbling Claws Third artifact with this set of abilities, even if its a minor set its nice to have redundancy
I like it the best in blue/green Town decks because that deck can splash other colors easily and doesnt care about giving them a token (a token thats way more of a liability in this format due to all the decent equipment)

From exile, you can cast the other side of the card, getting yourself a permanent, typically a few turns later, but not really putting yourself behind on cards
The flip gives you mana that is more versatile than a Black Lotus because you can choose a different color for each Treasure token
